I managed to launch my ant of 3 ants and finished the first level. Super fun since there is no predetermined way to beat the game. I kept repeating the first level to try to (mis)use the physics to get to the other side with as less ants as possible. I even tried to do it with one, but as you stated it can't be done. But please, if you managed to pull it off, let me know how and I will try it again.
Great job on your game, I hope you had fun!
